WINERED Exposure Time Calculator (calc_SN)

Description

This tool calculates the S/N for a given pair of the brightness and the exposure sequence (integration time, number of exposures, and the nodding pattern).

Input

Telescope		Select which telescope to use.
Mode		Select the mode to use (WIDE, HIRES-Y or HIRES-J).
Slit	μm	Select the width of the slit to use (100, 140 or 200 μm).
Season		Select Summer or Winter (this changes the thermal background).
FWHM	arcsecond	Give the FWHM of the target PSF.
Sampling		Select the sampling to calculate the S/N (per half resolution with the Nyquist sampling, or per pixel).
Dither		Select the nodding pattern (ABBA or OSO).
cor_factor		Correction factor for efficienty (default=1.0).
Flux input(s)	J mag	Check the option box and give the J mag
	Y mag	Check the option box and give the Y mag
	Wave,Flux	Check the option box and give a pair of wavelength in Å and flux in W/m^3.
Each exp	sec	Give the exposure time for each frame
Number exp	sec	Give the number of exposures including both target and sky positions
